• The output circuit is composed of open collector transistor outputs in the Darlington
connection, and connect to relays or photo-couplers.
• There exists collector to emitter voltage, V
CE
(SAT) of approx. 1V at transistor-ON, due to the
Darlington connection of the output or. Note that normal TTL IC cannot be directly connected
since it does not meet VIL.
• There are two types of output, one which emitter side of the output transistor is independent
and is connectable individually, and the one which is common to – side of the control power
supply (COM–).
• If a recommended primary current value of the photo-coupler is 10mA, decide the resistor
value using the formula of the right Fig.

• Feeds out the divided encoder outputs (A, B and Z-phase) in differential through each
line driver.
• At the host side, receive these in line receiver. Install a terminal resistor (approx. 330Ω)
(figure below (1))between line receiver inputs without fail.
• These outputs are not insulated.
Install toward the direction as
the fig. shows without fail.
